To all whom it 1110 3 (:oncevw:

Be it known that I, Hmmr G. Rms'r, a citizen of the United States, residing at Schenectady, inthe county of Schenectady, State of New York, have invented certain new and useful Improvements in Bearings, of which the following, is a. specification.

My invention relates to bearings and par' ticularly to bearings for machines of large diameter provided with vertical shafts. Such shafts carry the revolving member of the machine and are supported by-thrust bearings which in turn are supported by hearing brackets of large diameter fastened to the stationary members of the machine. It will, therefore, be seen that such bearing brackets act as beams supported at the outside ends on the stationary member andisupporting the revolving parts of the machine from the middle of the beam. Heretofore such bearing brackets have been constructed of two or more segments bolted together, -,because they are of 'such great size that they cannot otherwise be transported by railroads from the place of manufacture to the place where the machine is to be put into: operation. lVhen so constructed the beam consists essentially of two orimore parts joined together at the middle, which is the point of greatest stress, and consequently the parts of the bracket as well as the bolts firs-- toning the parts together mustbc made very heavy. 4

In accordance with my invention the revolving parts of the machine are supported upon a hub of large diameter which is constructcd as a single casting haying; an inner wall. an outer wall concentric with the inner wall and connected thereto by ribs, and the hub is supported on the stationary member of the ma'chineby means of relatively short braclictsor arms which are supported :at one end on the stationary frame and at the ntlrer end. are bolted 'to the outer wall of the hall. Ry constructing the bearing, brackets iri 'this way, the parts may be made of simple castings, and the joints in the beam 'arehear the ends thereof, the hub being made of as la'rge.-a diameter-as can be conveniently transported. The bearing, bracket as a whole may, therefore, be made much lighter than has been possible heretofore.

For a better understanding of my in ention referenccvmay be had to the following description taken in connection with the ac serene: castes sclrsnnc'rzmv, NEW YORK, ASSIGNOR 'io GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW Yomr.

companying drawing, in whiclr-the single figure is a view, partly in section, of a' inkivchine embodying my invention In the drawing, 1 have illustrated my bearing in a. dynamo electric machine of large diameter having a. stationary member 1, and a revolving member 2 mountesil on E. vertical shaft 3. The dynamo electric machine shown in the drawing is of the alternating current type having a stationary arn'mtnre and a. revolving field, and is driven by a motor (not showi-i) of any well known type, connected to the lower end of the shaft. My invention is not limited to dynamo electric machines, hon-ever, and may be used in any kind or type of machine of large diameter in wlnch the rotating member is supported on a vertical shaft.

The vertical shaft 3 has a sleeve bear-in" 4f r11 1 M I- b l; *5

\e wrung rac let hub is madeof asmgle casting having an inner wall 6, and an outer wall 7 concentric with the inner walh'the walls being connected togetl-ier by strengthening ribs 8. Theouter wall 7- 'inay be a] many sided polygon or maybe cylindrical. llns hub supports at its center the sleeve bearing l and the thrust bearii'ig 10, both. or which may be of any well known type.- he bearing bracketarms 9, which 10in the.

hub to the stationarymember, extend radially from the hub and are secured in position by suitable bolts, being fastened at one end tothe outer wall 7 and at the'other endto the stationary member 1 of the machine.

The hub and the bracket bearin arms to-' get-her constitute a beam supported at its end on the stationary member and carrying at the middle the weight of the revolving member 2 bearing bracket hubjis made as large as pos-- of the machine; The dianarterof the ihlc, and since it is a single casting, there' are no joints in the beam except where the bearing bracket arms arefastened there-to. These joints, however, are near the ends of the eam, and, therefore, the bearing is of maximum strength with minimum weight. It will also be seen that the bearingln'acket hub and the arms are very simple castings.

The thrust bearing 10 which I have shown in the drawing comprises two thrust plates 11. and 12. flange member 33 is to the shaft 3. The thrust pl 1. toned to the flange 13, so i at the the shah, and the revoivin." upon the lower thrust hate In a machine of large diameterhaving re-i volvingand stationary members and a vertical shaft on which said revolving member is mounted, a thrust bearing for said shaft;

and a bearing bracket for supporting said thrust bearing comprising a hub of large diameter formed of a. single casting having inner and outer COIICGIH'IHC walls connected together by ribs, and bearing bracket arms fastened at one end to the outer wall of said hub and at the other end to said stationary member, said arms extending radially from said hub, whereby said hub and said arms act together as a jointed beam jointed near the ends by which it is supported and carrying at its center the revolving'member of said machine. a i

In witness whereof, I have hereunto set my hand this 14th da of October, 1914. 4
